I found this book to be very helpful and quite life-changing. The book starts off by talking to you as the jealous person and, at first, makes you feel terribly guilty for being jealous and the liberties that you bestow on other people by being jealous, but then it explains the ways in which jealousy occurs and the reasons behind it and also explains the very surprising notion that no-one can make you jealous, only yourself. This had never occured to me before. As a jealous person, this book has been very helpful and has made me become more understanding of myself and would also be so to anyone who is in a relationship with a jealous person.
